- Description: The purpose of this research study was to determine the relationship between PsyCap and burnout in a service-related working environment that is somewhat unexplored, including the non-banking financial services sector. To achieve this purpose, a correlational research design was employed and the convenience, non-probability sampling method was utilised as the technique for sourcing participants. Data was collected by way of an online survey comprising of the PCQ-24, OLBI and a Biographical Section, which was distributed among 380 non-banking employees in the sample company, and a final sample size of N=88 was achieved. The two psychometric instruments utilised were both proven to be valid and reliable, thus increasing the credibility of the data obtained. The raw data was processed and analysed through statistical calculations, performed by a qualified Statistician, and included descriptive and inferential statistics in the form of cronbach’s alpha coefficients, pearsons correlations, t-tests, ANOVA’s, and linear regression for the data interpretation. The results revealed that there was a negative, statistically significant relationship between PsyCap and burnout, and that PsyCap explained 18% of the variance in burnout scores amongst the sample. In addition, statistically significant differences were found between burnout, disengagement, and position, as well as between PsyCap and some of its dimensions with gender, educational level, position, and department in terms of the demographic variables. The researcher has considered the ethical principles of autonomy, confidentiality, anonymity, and ownership of the data throughout the research process, and the research paper was submitted for assessment and ethical approval before commencement of this study. The primary aim of this research study was achieved in that a significant and negative correlation between PsyCap and burnout was revealed. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Industrial Psychology and Human Resources, 2021

- Description: South Africa is characterised by high levels of trauma and multiple forms of violence exposure which are said to be causal factors in post-traumatic stress disorder (PTSD). Culture is imperative in constructing the reality of individuals as it provides the templates which are used to describe, understand, predict, and control the world within which individuals exist. Culture is regarded as being influential on the ways in which individuals ascribe meaning and make sense of their traumatic experiences and symptoms. Culture is also integral to the healing process as it influences and guides the illness narrative created by individuals. The aim of this study is to understand the potential meanings attached to PTSD symptoms and the role of culture on these meaning ascriptions. These meanings are explored through the perception of Mental Healthcare Practitioners. The study uses qualitative methodology; specifically, an exploratory and descriptive design. The sample is identified through non-probability purposive sampling, and the data is collected through semi-structured interviews. The data is analysed using thematic analysis which identified major themes of understanding and acceptance. These themes followed a non-linear and interactive process, and present participants ascribing varying meanings to their trauma experience, PTSD symptoms and/or PTSD diagnosis. These meanings are discussed through the interpretivist lens of social constructionism. The findings of the study identified that individuals within the white English-speaking cultural group tend to understand their traumatic experience, their symptoms of PTSD and/or their PTSD diagnosis from an individualistic frame of reference, whilst individuals from the coloured English speaking cultural group tend to understand their traumatic experience, their symptoms of PTSD and/or their PTSD diagnosis from a collective frame of reference. , Thesis (MA) -- Faculty of Health Sciences, 2021

- Description: SMMEs are the backbone of both established and developing economies with their ability to contribute to a country’s GDP, create employment, stimulate innovation and create new revenue streams. In South Africa the majority of SMMEs do not reach the critical threshold period for sustainability, defined by the Small Enterprise Development Agency (SEDA) as three years. This study explores twenty-five barriers and influences (nine external and sixteen internal) as experienced by small businesses operating in the city of Port Elizabeth, and their effect on the sustainability and success of the small business. The internal barriers and influences are ranked according to their relative importance to business sustainability and success as viewed by small businesses in the city of Port Elizabeth. The research is exploratory in nature and was conducted using a structured questionnaire. The findings show that the nineteen barriers and influencers that are controllable within the business are all important to the success and sustainability of small businesses. Of these internal factors, the most important one relatively speaking is found to be the general management abilities of management, and the least important, relatively speaking, is the education levels of the non-management employees. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business Administration, 2021

Recreating a wetland at an abandoned saltworks : towards a rehabilitation plan

- Description: A saltworks at Swartkops Estuary was abandoned in 2018. While operational, the saltworks hosted some of the largest breeding colonies of several shorebird species in southern Africa and hosted thousands of Palearctic migrant waterbirds annually. The abandonment of the saltworks has resulted in the loss of the artificially managed hydrological regime and therefore the wetland function and habitat value of the site, and the rich and diverse avifauna that once occurred at the site have not returned. The rehabilitation of the saltworks as a wetland that functions as a waterbird sanctuary is currently being organised, and this research aimed to create a plan for implementing and monitoring the rehabilitation. In order to do so, the baseline environmental condition of the abandoned saltworks was established, the possible rehabilitation interventions necessary for rehabilitating the site were assessed, and the potential ecological implications of any interventions were investigated. The assessment of the saltworks’ baseline condition revealed that the site is now characterised by vast expanses of dry hypersaline sediment with sparse patches of monospecific vegetation and depauperate avifauna. The once rich and diverse waterbird communities have all but disappeared since the site was abandoned and are unlikely to return unless a managed hydrological regime is reinstated. Furthermore, it is improbable that salt marsh vegetation will cover the abandoned saltworks primarily due to the high sediment salinity that will persist unless the saltpans are flooded. The area will likely remain barren with little ecological value if no rehabilitation action is taken. Two potential rehabilitation options for reinstating a hydrological regime at the saltworks were identified: (1) pumping estuary water into all of the saltpans; or (2) pumping estuary water into some of the saltpans, while allowing the largest one to be filled with stormwater. Both options were deemed to be feasible; however, the second option will likely have lower running costs. The use of stormwater to fill the one saltpan is expected to result in brackish conditions initially, while the saltpans filled with estuary water would have salinity levels ranging from euhaline to slightly hypersaline. Both the stormwater and estuary water are rich in inorganic nutrients – the estuary water is rich in both dissolved inorganic nitrogen (DIN) and dissolved inorganic phosphorus (DIP), while the stormwater has an exceptionally high DIN content. This raised concerns of creating eutrophic wetlands with detrimental conditions such as algal blooms and a hypoxic water column. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2021

- Description: My thesis is a collection of poems that focuses on black mothering and motherhood, within the context of the Eastern Cape’s violent history, its oppressive patriarchal cultural traditions and religious structures. Drawing from my own experiences, my poems explore what Toni Morrison calls the historical ‘wounds’ of black women which are transferred to their daughters within everyday spaces like the kitchen and the lounge, through objects like tea cups, chair backs and the various foods that every black girl needs to be able to prepare in order to be ‘marriagable’, and how these continue to hurt and emotionally disfigure us. I also draw influence from Saidiya Hartman, Christina Sharpe and Tina Campt on black lives and the effects of slavery within their daily existences. And I am inspired by the intimacy and care with which Tadeusz Rosewicz writes about his relationship with his mother in Mother Departs and Sandra Cisneros’ use of interconnected vignettes to engage childhood, culture and community within marginalized space. Stylistically I am influenced by the structural innovations in Fred Moten’s The Little Edges and the dreamy landscape in the poetry of Federico Garcia Lorca. My collection includes prose and lyrical poetry, combining more formal sound and rhythmic structures with free verse, to bring to life motherhood and the narratives we carry from childhood into our adult lives.

- Description: In this work, the rheological properties of alumina slurries milled to different particle sizes were investigated. Viscosity increases as the particle size decreases. When increasing amounts of calcium hydroxide, strontium hydroxide or barium hydroxide are added, the viscosity first goes down and then goes up. This can be explained in terms of changes in pH and changes in ionic strength impacting on the surface potential of the particles in suspension. Adding the same concentration of different cations results in different viscosities, with the order being (from high to low viscosity) Ba>Sr>Ca. Effects of partial dissolution of and structural changes to the alumina particles at high pH cannot be excluded. In order to better understanding the different effects, it was attempted to measure the zeta potential of the slurries at different pH values. This resulted in highly positive zeta potential values over the complete pH range, without the observationof an iso-electric point. This does not fit to the observed changes in rheology and contrasts withliterature data. One explanation would be that the measurement system used is unsuitable to yield correct zeta potential values for the materials under investigation. , Thesis (MSc) -- Faculty of Science, Department of Chemistry, 2021

- Description: My thesis is a collection of poems which focus on human experiences related to my background. I grew up in a countryside village, freely experiencing nature in unrestricted walks to the rivers and mountains; communal living instilled in me the humanitarian values which I uphold to the present. I use short and long lyrical prose poems to bring life and humanise the untold or unexpressed stories of my community. My use of simple everyday language and clear, concrete but surprising images that resonate with deeper meanings and emotions is influenced by Seitlhamo Motsapi’s poems, especially his collection of poems titled earthstepper/the ocean is very shallow and Mxolisi Nyezwa’s poetry book, Song Trials. Spanish poems in English translations by the 20th century Spanish poets: Blas de Otero, Juan Roman Jimenez and Federico Garcia Lorca, published in the book titled Roots and Wings have had a huge impact on my construction of images. I also draw from the free-form and narrative prose poetry experiments of poets: Mangaliso Buzani, vangile gantsho and Ivy Alvarez. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 2021

My use of simple everyday language and clear, concrete but surprising images that resonate with deeper meanings and emotions is influenced by Seitlhamo Motsapi’s poems, especially his collection of poems titled earthstepper/the ocean is very shallow and Mxolisi Nyezwa’s poetry book, Song Trials. Spanish poems in English translations by the 20th century Spanish poets: Blas de Otero, Juan Roman Jimenez and Federico Garcia Lorca, published in the book titled Roots and Wings have had a huge impact on my construction of images. I also draw from the free-form and narrative prose poetry experiments of poets: Mangaliso Buzani, vangile gantsho and Ivy Alvarez. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 2021

- Description: Background: Schistosomiasis also known as Bilharzia is one of the most common parasitic water-borne disease of global health importance. This study investigated the KAP of Grades 4 to 7 children from 4 selected primary schools in the study area on schistosomiasis. Furthermore, using the secondary data, the researcher determined the prevalence of schistosomiasis in KwaNobuhle over a five-year period from 2014 to 2018 retrospectively. Methods: The study employed a quantitative, descriptive, cross-sectional survey research design approach similar to a study done by Parisi et al. (2019, p.1–14) on intestinal schistosomiasis. A structured, closed-ended, self-administered, Likert-scale questionnaire was used to collect data from 458 learners in Grades 4 to 7 and aged from 9 to 16 years. Data on retrospective prevalence was obtained from the District Health Information System (DHIS) and the National Health Laboratory Service (NHLS) within the Nelson Mandela Bay. The data was analysed using descriptive and inferential statistics. Results: The leaners’ overall knowledge and attitudes towards schistosomiasis were poor based on the overall low-knowledge scores, which was 46% in the lowest category from 0-19 points. Urinary schistosomiasis infections within the study area showed an increase from the years 2014 to 2017; but declined in the year 2018. Additionally, the males 99 (24%) had a higher prevalence compared to the females 6 (1%) (p=<0.0005, V= 0.33 medium). The highest rate of disease infections was found in individuals between the ages of 10 and 19 years (p=<0.0005, V=0.43 medium). Conclusion: In conclusion, the researcher found that the overall knowledge and attitudes towards schistosomiasis among the learners were poor. The study further revealed that the rate of urinary schistosomiasis infections within the study area had increased from the years 2014 to 2017; but had declined in the year 2018. Recommendations were made to emphasise the need for education and awareness programmes on the disease-transmission pattern and control measures. , Thesis (MTech) -- Faculty of Health Sciences, 2021

- Description: Score driven (SD) conditional volatility models allow for rich volatility dynamics and realistic distributional assumptions. These models link the evolution of time-varying volatility to the shape of the predictive density, which often results in models that are robust against outliers. These models also allow for conditional skewness. The combination of skewness and robustness may improve in-sample fit, conditional volatility forecasts and tail-risk forecasts. Therefore, this study proposes novel SD conditional volatility models with Skewed-t distributed innovations. For some of these models, the formof skewness partially negates robustness against outliers. This result demonstrates that the formof skewness requires careful consideration in the specification of SD conditional volatility models. The study also expands upon earlier observations that the assumption of negative conditional skewness may induce a form of volatility asymmetry in SD conditional volatility models that is incompatible with the leverage effect typically observed in equity markets. A simulation experiment shows that neglected leverage, therefore, biases maximum likelihood estimates. Additionally, the study considers SD conditional volatility models that account for leverage effects and have Skewed-t distributed innovations. An empirical application to the daily Johannesburg Stock Exchange (JSE) / Financial Times Stock Exchange (FTSE) All Share Index returns demonstrates the utility of SD conditional volatility models with Skewed-t distributed innovations. Extensions of these models that account for leverage prove competitive with more traditional conditional volatility models in terms of in-sample fit and tail-risk forecasts. These results suggest that the models considered in this study are useful within the context of financial risk management. , Thesis (PhD) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2021

- Description: The false codling moth (FCM), Thaumatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae) is endemic to southern Africa, and strongly associated with citrus. As South African citrus production is mainly for export to foreign markets, the market access risk due to the phytosanitary status of this pest is considerable and its control is therefore imperative. Various control measures as part of a rigorous integrated pest management (IPM) programme targeted against T. leucotreta have been effective at suppressing the pest in citrus, but there is still a growing need for continued improvement of the programme and augmentation of the available control options. Of these control options, biological control, particularly the use of Cryptophlebia leucotreta granulovirus (CrleGV-SA), is a key component of IPM in citrus orchards and it has been very successful at reducing T. leucotreta populations in the field for almost two decades. There is however, a growing need for more baculovirus variants with an improved virulence against T. leucotreta for a more efficient pest management system. The newly identified insect virus, Cryptophlebia peltastica nucleopolyhedrovirus (CrpeNPV) offers a unique opportunity for an additional biopesticide in IPM for control of T. leucotreta in the field. This study aimed to conduct serial passaging of CrpeNPV through a heterologous host, T. leucotreta, in order to determine the potential for improved virulence or speed of kill against it. In order to select for a variant of CrpeNPV with improved virulence against T. leucotreta, a high dose (LC90) of the virus OBs was used to perform 12 serial passages through T. leucotreta larvae in surface-dose bioassays. Whole genome sequencing and analysis of the passaged virus, along with restriction endonuclease profiling in silico was performed to determine if the genetic identity of the virus had changed during serial passage, in relation to the original virus. These analyses indicated that the dominant genotype of CrpeNPV was maintained following 12 serial passages through the heterologous host. The biological activity of the passaged virus, along with the original virus was evaluated against neonate T. leucotreta in surface-dose bioassays and compared. Results from dose-response bioassays showed that the virulence of CrpeNPV did not improve after 12 serial passages. The LC50 values of the passaged virus and the original virus were estimated at 1.96 × 104 and 1.58 × 104 OBs/ml, respectively, whereas the LC90 values were estimated at 3.46 × 104 OBs/ml for the passaged virus and 3.68 × 104 for the original virus. Similarly, the results from time-response bioassays showed that the speed of kill of CrpeNPV did not improve after 12 serial passages. The LT50 values of the passaged virus and the original virus were 88.44 hours (3 days and 16 hours) and 83.74 hours (3 days and 12 hours), respectively, whereas the LT90 values were 115 hours (4 days 19 hours) for the passaged virus and 102 hours (4 days 6 hours) for the original virus. The virulence and speed of kill of the passaged virus decreased significantly, in relation to the original virus. When the full genome of the passaged virus was sequenced and analysed, only a few SNPs were detected in the viral genome, in comparison to the original virus. No detectable difference in REN digestion patterns were observed following REN analysis of gDNA of the passaged virus with several restriction enzymes in silico. The results for this study suggest that CrpeNPV may already be optimally suited to the heterologous host as it persists under these conditions without significant changes to the genome. These results have positive implications for the genetic integrity of CrpeNPV as a potential biocontrol agent in the field. This study is the first to report the virulence selection of CrpeNPV by serial passage through a heterologous host, and also the first to record bioassay data in terms of dose response (or lethal concentration) against T. leucotreta second instars. The data obtained have added to the knowledge about interactions between CrpeNPV and its heterologous host, and may be fundamental to continued investigation into the effect of serial passage on pathogenicity and genetic diversity of CrpeNPV. , Thesis (MSc) -- Faculty of Science, Biochemistry and Microbiology, 2021

- Description: Dissemination, adoption and continued use of adopted technologies are key requirements for improved smallholder farmers’ productivity. In an attempt to improve smallholder agricultural production and creating a resilient smallholder agricultural sector, many technologies such as the in-field rainwater harvesting technique (IRWHT) have been put in place. IRWHT has a tremendous potential for improving livelihoods of rural smallholder farmers, thus decreasing their vulnerability to vagaries of climate change. However, though IRWHT was promoted for agricultural crop production improvement, smallholder farmers discontinued its adoption. This study critically assessed the perception of smallholder farmers in Raymond Mhlaba Local Municipality (RMLM) on the use of the in-field rainwater harvesting technique to assess the underlying factors that led to IRWHT dis-adoption. This study adopted a descriptive study design; purposive sampling was used to select a sample of 120 smallholder farmers that initially adopted IRWHT. Data was gathered through a face-to-face interview and with a pre-tested semi-structured questionnaire. Descriptive statistical analysis frequency count, percentages, means and standard deviation were used for quantitative data analysis. The findings revealed that 96percent of smallholder farmers dis-adopted IRWHT after initial adoption. Moreover, IRWHT was dis-adopted 5-8 years post adoption. Critical reasons behind discontinuity include small land size (23percent), lack of reliable water source (18percent), complexity of IRWHT, continual extension support (17percent) and IRWHT taking up much space (13percent), amongst others. This study also revealed that farmers’ perception towards the innovation attributes of IRWHT, in relative advantage over economic returns such as profitability, had an impact on dis-adoption of IRWHT, with a negative farmers’ perception (𝑥̅ = 2.95). Complexity of IRWHT was associated with discontinuity of IRWHT by smallholder farmers in RMLM, with the majority (60percent) of smallholder farmers indicating that IRWHT was labour intensive. Some (39.9percent) stated that implementation of IRWHT was time consuming. Innovation attributes that led to a high rate of initial adoption were relative advantage with better yield (𝑥̅ = 4. 38) and compatibility. Smallholder farmers indicated that IRWHT can be implemented with cheaper and available working tools (𝑥̅ = 3.54). On trialability, smallholder farmers indicated that IRWHT was triable in different seasons and on observability smallholder farmers had a positive perception (𝑥̅ = 3.81) towards observable improved crop yield. Smallholder farmers had a positive perception (𝑥̅ = 4.14) of extension service support during the scaling-up of IRWHT although they indicated that the extension service support had ceased. , Thesis (MSc) -- Faculty of Science and Agriculture, 2021

- Description: Smart Factories are a key component of Industry 4.0 and have over the last few years become a relevant topic in manufacturing across all industries. The dairy industry is no different and many of the leading dairy manufacturers have adopted many Smart Factory components and technologies. These Smart Factory components and technologies have led to change in the workplace compared to the traditional way of manufacturing. With any organisational change, it is important to consider the impact that it has on the employees of the organisations and what their attitudes and perceptions towards these changes are. When understanding employees’ attitude and perceptions of changes or factors with regard to technological changes in the workplace, organisations can manage and improve the adoption of Smart Factory Adoption. There is limited research on Smart Factory adoption in the dairy manufacturing industry in South Africa. A conceptual model was proposed based on a literature study, identifying the main factors that influence the adoption of a Smart Dairy Factory. A hypothesised model was tested by conducting a research study with a sample of employees from different hierarchical levels in a dairy factory. The questionnaire was distributed to employees and management in the organisation. The results and insights obtained, determined the factors that influence the adoption of a Smart Dairy Factory in South Africa. This study identified that the independent factors of Individual Factors, Job Security, Perceived Benefits, Trust, Company Culture towards new innovations/technologies, Company Culture with employee involvement towards new innovation/technologies, Cost and Resources, Employee perceived value of Skills and Training and Organisational Skills and Training development all have a significant positive effect on Smart Dairy Adoption. The study further identified that the Job Level of employees have a significant effect on all of the factors influencing the Smart Dairy Adoption. This is a significant finding due to the fact that management, in general, is responsible for implementing Smart Factory technologies, whereas the general workforce are the ones accepting and being affected most by the change. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

- Description: Estuaries are complex systems and should be defined as social-ecological systems. This study investigated whether the Swartkops Estuary was managed as a socialecological system and also argued for the resource to be characterised as a commonpool resource due to its ‘open access’ nature and being utilised by many users. People often live in close proximity to estuarine resources. This means that the ecological component of the estuary cannot be managed separately from the social system. There are feedbacks that result from the interactions taking place between the ecological and social components and these need to be considered. Furthermore, the interactions between humans and estuaries are complex and do not change in a linear, predictable manner. The research methods investigated two research aims: (i) to investigate whether social-ecological systems approaches are currently being adopted in the Swartkops Estuary; and (ii) the sustainable management of the Swartkops Estuary and potentially other estuaries in South Africa. The following research objectives formed the basis of this study: (i) to examine the current management system of the Swartkops Estuary; (ii) to determine and map the social and institutional actors for the Swartkops Estuary; (iii) to analyse the views of local stakeholders, authorities (policy makers) and policy implementers on the use of a social-ecological systems approach in the integrated management of the Swartkops Estuary; and (iv) to illustrate the potential advantages of adopting a social-ecological systems approach for ecosystem services and society. A mixed-method research design was applied in this study using questionnaires, semistructured interviews and focus groups discussions as data collection methods. The ecosystem services approach is one of the accepted approaches that links humans and ecosystems and the results of this study has demonstrated that the habitats of the Swartkops Estuary provide ecosystems systems to various stakeholders. Through the application of the natures’ contribution to peoples lens, this study has shown that estuaries contribute both positively (ecosystem services) and negatively (ecosystem disservices) to people. The findings of this study have revealed that the Swartkops Estuary faces sustainability challenges related to free-riding and the tragedy of the commons dichotomy. The governance of the Swartkops Estuary is weak due to the limited implementation of policy and regulatory requirements. This inadequacy in implementation has led to the overexploitation of living resources in the Swartkops Estuary because the ‘rulesin use’ are not respected and adhered to by users. This study therefore proposes guiding principles and practical implications for each of the following dimensions: (i) social-ecological systems; (ii) common-pool resources; and (iii) governance for integrated sustainable estuarine management. Challenges faced by estuaries are not only of ecological, social or economic nature; they involve a combination of all three. The sustainability of estuaries is therefore complex and requires management and governance that is designed to cope with, and adapt to, the social-ecological system changes. The novel contribution of this study is moving away from the orthodox approaches of examining the Swartkops Estuary by applying the SES approach to assess the governance of the estuary as a common-pool resource. , Thesis (DPhil) -- Faculty of Humanities, Development Studies, 2021

- Description: Estuaries are complex systems and should be defined as social-ecological systems. This study investigated whether the Swartkops Estuary was managed as a socialecological system and also argued for the resource to be characterised as a commonpool resource due to its ‘open access’ nature and being utilised by many users. People often live in close proximity to estuarine resources. This means that the ecological component of the estuary cannot be managed separately from the social system. There are feedbacks that result from the interactions taking place between the ecological and social components and these need to be considered. Furthermore, the interactions between humans and estuaries are complex and do not change in a linear, predictable manner. The research methods investigated two research aims: (i) to investigate whether social-ecological systems approaches are currently being adopted in the Swartkops Estuary; and (ii) the sustainable management of the Swartkops Estuary and potentially other estuaries in South Africa. The following research objectives formed the basis of this study: (i) to examine the current management system of the Swartkops Estuary; (ii) to determine and map the social and institutional actors for the Swartkops Estuary; (iii) to analyse the views of local stakeholders, authorities (policy makers) and policy implementers on the use of a social-ecological systems approach in the integrated management of the Swartkops Estuary; and (iv) to illustrate the potential advantages of adopting a social-ecological systems approach for ecosystem services and society. A mixed-method research design was applied in this study using questionnaires, semistructured interviews and focus groups discussions as data collection methods. The ecosystem services approach is one of the accepted approaches that links humans and ecosystems and the results of this study has demonstrated that the habitats of the Swartkops Estuary provide ecosystems systems to various stakeholders. Through the application of the natures’ contribution to peoples lens, this study has shown that estuaries contribute both positively (ecosystem services) and negatively (ecosystem disservices) to people. The findings of this study have revealed that the Swartkops Estuary faces sustainability challenges related to free-riding and the tragedy of the commons dichotomy. The governance of the Swartkops Estuary is weak due to the limited implementation of policy and regulatory requirements. This inadequacy in implementation has led to the overexploitation of living resources in the Swartkops Estuary because the ‘rulesin use’ are not respected and adhered to by users.

- Description: The purpose of the study was to conduct an analysis on whether the foreign policy under the Zuma administration served to protect and promote human rights or whether it served national interest. This was done by analyzing foreign relationships South Africa had under the Zuma administration. The analysis of the research was guided by answering whether the initial 1993 ANC human rights orientated foreign policy was still practiced or whether it was more focused on national interest. Previous work has failed to address the relationships South Africa had with undemocratic and/or authoritarian states during Zuma’s tenure, this includes the arms deal trade with the Arabic states, Russia and China, which resulted in the overlooking of human rights violations by its foreign relations, which resulted in the 1993 ANC proclamations of a human rights orientated foreign policy being no longer practiced. The study followed the qualitative research approach, with the use of documentary analysis for the purpose of the literature review, with the use of case studies. The findings hold that the South African foreign policy during the Zuma administration prioritized national interest and the protection of its foreign relations. The findings also highlight the importance of public participation in international agreements prior to the legalization of them. This study also provided suggestions for future research projects, which will allow for the public to be involved in decisions - that will affect their livelihood - that are taken by the state and to be able to hold the executive accountable for the decisions they make. , Thesis (MA) -- Faculty of Humanities, 2021

- Description: South Africa’s automotive industry is a vital element in the country’s economy. This sector has been a strategically important sector in South Africa, and it is imperative to ensure not only the sustainability of the automotive sector in the country, but also the continued growth of the industry. This study addressed the determinants of South Africa’s automotive exports to BRICS countries. The main aim of the study is to examine South Africa’s automotive industry trade elasticity to economic performance in BRICS countries. An econometric assessment was done using different estimation techniques, namely Dynamic Panel Data General Method of Moments (GMM) on annual data from 2000 to 2016, quantile regression for the same period, and ANOVA analysis. This study used eight endogenous variables in explaining determinants of South African automotive export to BRICS countries. The results from the GMM technique suggested that only four variables out of eight variables were statistically significant, namely, automotive exports lagged once, corporate tax, research and development (R&D), and real exchange rates. Gross Domestic Product (GDP), Foreign Direct Investment (FDI), trade openness, and R&D all reduced automotive exports in South Africa. Quantile regression provided difference compared to the GMM dynamic panel data analysis. In the panel data analysis, corporate tax was positive, while in the quantile regression only Brazil’s corporate tax had a positive effect on South African automotive exports. FDI results in panel data GMM results were the same as quantile, while other variables results were not consistence with the dynamic panel data GMM results. The ANOVA results suggested that significant differences between BRICS countries impact on South Africa’s automotive exports. The findings indicate that South African automotive exports to BRICS have been proven to be elastic in four variables., namely, automotive exports lagged once, corporate tax, research and development (R&D), and real exchange rates. The South African automotive industry implemented policies such as the Motor Industry Development Programme (MIDP) and the Automotive Production and Development Programme (APDP); however, these policies failed to realise the targets set by the v industry. On the policies regarding automotive exports in South Africa, it is equally important to pay attention to corporate tax in South Africa as well as in other BRICS countries. BRICS economies lack policy synchronisation, hence the adverse impact on South African automotive exports. South Africa’s BRICS counterparts are knowledge-driven economies. Developing a strong human base is required in the sector. In addition, there is a need for BRICS countries to have a free trade agreement (FTA) to enhance trade amongst member states. Having free trade could help to make BRICS economic integration more meaningful to BRICS countries and the region. , Thesis (PhD) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2021

- Description: Child health outcomes in Ghana and Sub-Saharan Africa have remained poor compared to other regions of the world. More than half of the global deaths among children under five years of age occur in sub-Saharan Africa. Neonatal and under five child death rates continue to remain high in Ghana, mainly because of the high death rates recorded in the rural areas. Adequate and prompt utilisation of child healthcare services contributes to improved child health outcomes. Despite all the efforts to improve child health, the utilisation of child healthcare services in rural areas in Ghana such as the Nkwanta South Municipality has remained poor. The purpose of this study was therefore to develop strategies that could facilitate the utilisation of child healthcare services by caregivers for their children in need in the Nkwanta South Municipality, Ghana. A qualitative approach, using an exploratory, descriptive and contextual design was implemented for this study. The research comprised the following three phases. Phase One comprised the empirical phase which explored and described the experiences of three groups of participants namely, nurses who rendered child healthcare services in both hospitals and clinics; caregivers of children under five years of age who utilised the available child healthcare services and caregivers of child under five years of age who did not utilise the available child healthcare services. Data was collected through semi-structured interviews conducted with these participants and analysed qualitatively according to the six steps outlined in Creswell (2014:197). Four main themes and 10 sub-themes emerged from the data analysis and were presented and discussed. Phase Two consisted of the compilation of the conceptual framework using the survey list by Dickoff, James and Wiendenbach (1968:423). The conceptual framework was compiled based on the findings of the empirical phase and the WHO Health for All model which was the theoretical framework that underpinned this study. The conceptual framework was also later used as the lens for the development and description of the strategies to facilitate the utilisation of child healthcare services by caregivers for their children in need in Phase Three. Phase Three of the study was the final phase of the research and it involved the development and description of the strategies that could be used by nurses to facilitate the use of child healthcare services by caregivers for their children in need in Nkwanta South Municipality, Ghana. Five strategies were developed and described in this phase. The five strategies were: training and deployment of nurses; capacity building for nurses to support quality child healthcare delivery; resourcing healthcare facilities; community engagement and participation and stakeholder collaboration. The evaluation criteria of Chinn and Kramer (2011:197) were used by six experts to evaluate the strategies. The strategies were evaluated and found to be understandable, clear, simple, applicable and significant to nursing practice. It can thus be concluded that the purpose of the study was achieved since strategies were developed to facilitate the utilisation of child healthcare services by caregivers for their children in need in the Nkwanta South Municipality, Ghana. , Thesis (PhD) -- Faculty of Health Sciences, 2021

- Description: The outbreak of the Covid 19 pandemic and the lockdown restrictions imposed by the government in March 2020 exacerbated uncertain conditions of the weak South African business environment. This meant that SME owners and managers in different sectors had to implement strategies to manoeuvre the further weakened and unprecedented business environment. To investigate this, the research question asked was: what sustainable strategies will SME owners and managers craft and implement to use post the lockdown period? The study analysed strategies before, during, and post the hard lockdown period to provide insight into how SMEs adopted to the uncertain business environment. This study interviewed twenty (20) SMEs in different sectors in Gauteng to explore strategies that SME owners and managers used to sustain their businesses prior to, during, and post the level 5 and level 4 lockdown. The study revealed strategies employed by SME owners across five sectors. Furthermore, the study indicated that during the hard lockdown, owners used a “wait and see” strategy in different degrees. Post the level 5 and 4 lockdown, different sectors were innovating, cost cutting, and digitisation according to their level of comfortability and diversification. The study reveals that strategic planning was missing prior, during, and post the level 4 and 5 lockdowns, despite SME owners’ educational background. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021
